  By the way, a baby carriage having a lock operation mechanism as shown in FIG. 10 is also known. The lock operation mechanism in FIG. 10 includes a locking member 100 and an operation member 101. The locking member 100 is attached to the hand barb 102 by a rotation shaft 103 and can rotate around a rotation axis perpendicular to the longitudinal direction of the hand barb 102. The locking member 100 is urged clockwise by a spring or the like in the drawing. In this state, the locking member 100 locks the movement of the operation member 101 so that the operation member 101 is not operated by mistake.

  When switching the stroller between the unfolded state and the folded state, first, the handle 102 near the locking member 100 is gripped (FIG. 10A), and the locking member 100 is moved forward against the biasing force with the thumb. Rotate to the side, that is, counterclockwise in the figure, to unlock the operating member 101. Next, the handclaw 102 is lightly changed while maintaining the state of the thumb, and the operation member 101 is clamped while the grasping protrusion 101a of the operation member 101 is hooked with the index finger and the middle finger (FIG. 10B). In this state, by pulling the operation member 101 toward the front side along the longitudinal direction of the push bar 102, the lock by the lock mechanism is released, and the baby carriage can be switched between the expanded state and the folded state.

  However, according to this lock operation mechanism, as is clear from the difference in the arrangement of the hands shown in FIGS. 10A and 10B, the operation of releasing the lock by the lock member 100 is possible. The operation of pulling the operation member 101 toward the near side in order to release the lock by the lock mechanism is an entirely independent operation. Therefore, it is difficult to smoothly perform the operation of the lock operation mechanism by a series of operations in order to release the lock that maintains the expanded state or the folded state.

  The connecting rod 80 extends in parallel to the support tube 40b of the hand rod 40 when the hand rod 40 is in the back pushing position. A locking projection 81 is provided on the outer surface of the upper portion of each of the connecting rods 80 (FIG. 3). Locking protrusions 51 having the same shape as the locking protrusions 81 are provided on the outer surfaces of the armrests 50 (FIG. 2). The locking projection 81 of the connecting rod 80 and the locking projection 51 of the armrest 50 are arranged concentrically with respect to the shaft member 43 in FIGS. Further, locking members 44 having locking portions (not shown) that can be locked with these locking projections on the concentric circles are attached to the left and right support tubes 40 b of the hand bar 40. The locking member 44 is formed in a cylindrical shape and is movable in the longitudinal direction along the support tube 40b of the hand barb 40. The locking member 44 is urged downward, that is, toward the lower end by an urging means (not shown). ing.

The locking member 44 and the locking protrusion 81 of the connecting rod 80 or the locking protrusion 51 of the armrest 50 move the locking member 44 upward along the support tube 40b of the hand bar 40 against the urging force. Thus, when the locking member 44 is returned to the original position, it is locked again. The hand barb 40 can be swung back and forth in a state in which the locking member 44 and the locking protrusion 81 or the locking protrusion 51 are unlocked, and switch between the back pressing position and the facing pressing position. Can do. That is, when it is desired to place the hand pusher 40 in the back push position (FIG. 2), the lock member 44 and the lock protrusion 81 of the connecting rod 80 are locked, and the hand pusher 40 is brought into the facing push position (FIG. 3). If you want to, the engaged a locking projection 5 1 of the locking member 44 and the armrest 50. When the hand push rod 40 is in the back push position, as shown in FIG. 2, the hand push rod 40, the front leg 20, and the connecting rod 80 are parallel to each other. Further, when the hand barb 40 is in the face-to-face pressing position, as shown in FIG. 3, the hand barb 40 and the rear leg 30 are parallel.

  Next, a lock mechanism that maintains the unfolded state or the folded state will be described. FIG. 5 is a partial perspective view of the lock mechanism in the locked state, and FIG. 6 is a partial perspective view of the lock mechanism in the unlocked state.

  The lock mechanism includes an unlocking member 45 attached to each of the left and right support pipes 40b of the hand push rod 40, and a lock member 82 attached to each of the left and right connecting rods 80. The unlocking member 45 is formed in a cylindrical shape and is movable in the longitudinal direction along the support tube 40b of the hand barb 40. The unlocking member 45 is urged downward, that is, toward the lower end by an urging means (not shown). ing. The lock member 82 is formed in a cylindrical shape, is movable in the longitudinal direction along the connecting rod 80, and is urged downward, that is, toward the lower end by an urging means (not shown).

  In particular, as clearly shown in FIG. 6, an engaging protrusion 82 a protruding downward is formed on the outer lower surface of the lock member 82. In addition, an engagement convex portion 82 b that protrudes downward is formed on the inner lower surface of the lock member 82. In the deployed state of the baby carriage 1, the engaging protrusions 82 a of the lock member 82 engage with the engaging recesses 42 a of the bracket 42 formed in a complementary manner, and prevent the bracket 42 from rotating around the shaft member 43. Similarly, the engagement protrusion 82b of the lock member 82 engages with the engagement recess 17a of the engagement panel 17 formed in a complementary manner, and the rotation of the engagement panel 17 around the shaft member 43, that is, the shaft member 43. The rotation of the side frame 18 of the surrounding seat 11 is prevented. That is, in FIG. 5, the lock mechanism is in a locked state. As a result, the stroller 1 maintains the unfolded state.

  On the upper part of the lock member 82, an operation plate 83 is provided that protrudes to the outside, that is, the support tube 40b side of the hand barb 40. The operation plate 83 is arranged so as to form a plane perpendicular to the longitudinal direction of the connecting rod 80.

  The unlocking member 45 has an unlocking rod 46 that protrudes inward, that is, toward the connecting rod 80 side. When the hand push rod 40 is in the back pushing position, the lock release rod 46 of the lock release member 45 is relatively positioned between the lock release rod 46 and the operation plate 83 so that the lock release rod 46 is disposed immediately below the operation plate 83 of the lock member 82. The correct position is set. The unlocking rod 46 of the unlocking member 45 and the operation plate 83 of the locking member 82 do not hinder the swinging motion of the hand pushing rod 40 before and after.

  The lock release member 45 moves upward along the support tube 40b by operating a lock operation mechanism 70 provided on the hand bar 40. By the upward movement of the unlocking member 45, the unlocking rod 46 of the unlocking member 45 engages with the operation plate 83 of the locking member 82, and the locking member 82 also moves upward. By the upward movement of the lock member 82, the engagement between the engagement convex portion 82 a of the lock member 82 and the engagement concave portion 42 a of the bracket 42, and the engagement between the engagement convex portion 82 b of the lock member 82 and the engagement panel 17. The engagement with the joint recess 17a is released. Therefore, the bracket 42 around the shaft member 43 and the side frame 18 of the seat 11 around the shaft member 43 can be rotated. That is, in FIG. 6, the lock mechanism is in the unlocked state. As a result, the baby carriage 1 can be switched from the expanded state to the folded state.

  As is clear from the structure of the lock mechanism, when the hand barb 40 is in the face-to-face push position as shown in FIG. 3, it is not possible to release the lock by the lock mechanism even if the lock operation mechanism 70 is operated. Can not. That is, since the lock release member 45 and the lock member 82 are separated from each other, even if the lock operation mechanism 70 is operated, the lock member 82 cannot be moved upward by the upward movement of the lock release member 45.

  Next, an operation for folding the baby carriage 1 will be described. First, if the hand push rod 40 is in the face-to-face push position, the hand push rod 40 is moved from the face push position (FIG. 3) to the back face push position (FIG. 2) before the folding operation.

  In the state where the push bar 40 is set to the back pushing position, the left and right lock operation mechanisms 70 of the push bar 40 are simultaneously operated, and the lock member 82 is moved upward via the lock release member 45 to lock the lock mechanism. To release. That is, the engagement between the lock member 82 and the bracket 42 and the engagement between the lock member 82 and the engagement panel 17 are released. In this state, when the push bar 40 is pulled up rearward and upward, the member connected by the shaft member 43 together with the bracket 42, that is, the armrest 50, the side frame 18, and the connecting bar 80 are intermediate portions of the rear leg 30. Rotate slightly around 30a clockwise in FIG. Next, by pushing down the push bar 40 downward, the member connected by the shaft member 43 together with the bracket 42 rotates further in the clockwise direction while receiving assistance by gravity. By such an operation, the baby carriage 1 is finally switched to the folded state as shown in FIG.

  As shown in FIG. 4, in the stroller 1 in the folded state, the push bar 40 and the front leg 20 are disposed substantially parallel to each other, and the push bar 40 is disposed at a lower position than when the stroller 1 is deployed. Has been. Therefore, the folded baby carriage 1 has a compact size in the front-rear direction and the vertical direction as compared with the unfolded baby carriage 1, and is in a state suitable for storage.

  In the folded state of the baby carriage 1, the engaging projection 82 a of the lock member 82 engages with another engaging recess (not shown) of the bracket 42 that is formed in a complementary manner, and prevents the bracket 42 from rotating around the shaft member 43. To do. Similarly, the engagement protrusion 82b of the lock member 82 engages with another engagement recess of the engagement panel 17 formed in a complementary manner, and the rotation of the engagement panel 17 around the shaft member 43, that is, the shaft member. The rotation of the side frame 18 of the seat 11 around 43 is prevented. That is, in FIG. 4, the lock mechanism is in a locked state. As a result, the stroller 1 maintains the folded state.

  In order to switch the stroller 1 from the folded state to the unfolded state, a procedure reverse to the above-described folding operation may be performed. That is, the lock mechanism 70 is unlocked by simultaneously operating the left and right lock operation mechanisms 70 of the hand bar 40 and moving the lock member 82 upward via the lock release member 45. Next, by pulling up the hand bar 40 upward, the members connected by the shaft member 43 together with the bracket 42, that is, the armrest 50, the side frame 18, and the connecting bar 80 are shown in FIG. By rotating clockwise, the baby carriage 1 is switched to the deployed state and is locked by the lock mechanism so as to maintain the deployed state again.

  Next, the lock operation mechanism 70 will be described. FIG. 7 is a partial perspective view of the lock operation mechanism 70, and FIG. 8 is a longitudinal sectional view of the lock operation mechanism 70. The lock operation mechanism 70 includes an operation member 71, an engagement pin 72 that is an engagement member, a wire fixing pin 73, and an operation wire 74.

  The operation member 71 is formed in a cylindrical shape and is movable in the longitudinal direction along the support tube 40 b of the hand barb 40. In a state where the operation member 71 is attached to the hand bar 40, the upper part is expanded outward and the lower part is curved inward. As a result, as shown in FIG. 8, an annular space 75, or a space 75 at least in the left-right direction, is formed between the upper portion of the operation member 71 and the support tube 40 b of the hand barb 40. On the other hand, the lower part of the operation member 71 is solid.

  A locking pin 72 is inserted into the side surface of the operation member 71 from the corresponding hole 71a in the upper part in the left-right direction, and the wire fixing pin 73 is inserted through the corresponding hole 71b in the lower part from the hole 71b. . That is, the locking pin 72 is inserted into the operation member 71, but its tip does not penetrate the operation member 71. A circular hole 40c having substantially the same diameter as that of the locking pin 72 is formed in the support tube 40b of the push bar 40 so that the locking pin 72 is inserted therethrough. Further, a long hole 40d extending in the longitudinal direction is formed at a corresponding position in the support tube 40b of the hand barb 40 so that the wire fixing pin 73 is inserted therethrough.

  The locking pin 72 is a rod-shaped member having a small-diameter pin main body 72a and a large-diameter pressing portion 72b. A coil spring 76 is disposed between the pressing portion 72 b of the locking pin 72 and the support tube 40 b of the hand bar 40 in a state where the locking pin 72 is inserted into the operation member 71. At this time, the pin main body 72 a of the locking pin 72 is inserted through the coil spring 76. The pressing portion 72b of the locking pin 72 protrudes outward from the operation member 71 through the hole 71a. That is, the locking pin 72 is disposed integrally with the operation member 71 and locks the movement of the operation member 71.

  The wire fixing pin 73 penetrates the operation member 71 and is fastened with a nut or a rivet so that the end portion does not come off. The operation wire 74 is disposed in the hollow support tube 40b of the hand bar 40. In the support tube 40 b, one end of the operation wire 74 is connected to the wire fixing pin 73 and the other end is connected to the lock release member 45. As described above, when the unlocking member 45 is biased downward, the wire fixing pin 73 connected to the unlocking member 45, and hence the operation member 71 into which the wire fixing pin 73 is inserted are also downwardly applied. It is energized.

  FIG. 9 is a diagram for explaining the operation of the lock operation mechanism for releasing the lock of the lock mechanism. The lock operation mechanism shown in FIG. 9A shows the same state as the lock operation mechanism shown in FIGS. At this time, the wire fixing pin 73 is disposed below the long hole 40d extending in the longitudinal direction of the support tube 40b.

  In order to unlock the lock mechanism, from this state, first, the pressing portion 72b of the locking pin 72 is pressed against the urging force of the coil spring 76 in the direction toward the support tube 40b of the hand barb 40. Then, it is immersed in the space 75 (FIG. 9B). Thereby, the locking of the operation member 71 and the locking pin 72 is released. Next, the operation member 71 is moved upward along the support tube 40b of the hand barb 40 (FIG. 9C). At this time, the upward movement of the locking pin 72 is restricted by the circular hole 40c of the support tube 40b passing therethrough. On the other hand, the wire fixing pin 73 moves upward in the long hole 40d of the support tube 40b. The upward movement of the operation member 71 is caused by contact between the locking pin 72 and the inner wall surface of the space 75 of the operation member 71, for example, the lower end surface, or the wire fixing pin 73 and the upper portion of the long hole 40d of the support tube 40b. It is regulated by the contact.

  When the wire fixing pin 73 moves upward together with the operation member 71, the operation wire 74 having one end coupled to the wire fixing pin 73 also moves upward. As a result, the unlocking member 45 connected to the other end of the operation wire 74 also moves upward, and the lock mechanism is unlocked. Since the unlocking member 45 is biased downward as described above, the lock operating mechanism is automatically shown in FIG. 9D when the force that moves the operating member 71 upward is released. Return to the state. As a result, the pressing portion 72 b of the locking pin 72 returns to the state shown in FIG. 9A accommodated in the hole 71 a of the operation member 71.

  A series of operations from FIG. 9A to FIG. 9D to be in the state of FIG. 9A again hold the upper part of the operation member 71 with the thumb placed below, or This is done by holding the lower part of the operation member 71 so that the thumb is positioned upward and pushing the locking pin 72 with the thumb or other fingers. That is, the direction in which a force is applied to grip the operating member 71 and the direction in which a force is applied to push the locking pin 72 are the same. Further, since the locking pin 72 is disposed integrally with the operation member 71, the pressing of the locking pin 72 and the gripping of the operation unit main body 71 can be performed simultaneously. Therefore, the operation member 71 can be moved upward in this state, that is, after the locking pin 72 is pushed in, without changing the arrangement of each finger or the palm. For this reason, according to the lock operation mechanism which concerns on this invention, in order to cancel | release the lock which maintains the expansion | deployment state or folding state of the baby carriage 1, it can operate simply and smoothly, and the convenience improves.

  In the embodiment described above, the operation member 71 and the support tube 40b are locked by passing the lock pin 72 as a lock member through the support tube 40b of the hand barb 40. However, as long as the operation member 71 is disposed integrally and the movement of the operation member 71 is locked and pressed in the direction toward the push bar 40, the lock is released. The member may have any configuration. For this reason, the fact that the locking member is arranged integrally with the operating member includes not only the mode in which the locking member is included in the operating member as in the above-described embodiment, but also a mode in which the locking member is adjacent or close. It is out.
